JOURNAL-BOX COOLER.

Specification of Letters Patent. Patented June 17, 1913.

Application filed February 24, 1913. Serial No. 750,397.

To aZZ 1071077?, it may concern:

Be it known that T, JErrERsoN D. MET- UALF, a citizen of the United States, residing at Gloster, in the county of Amite and State of Mississippi, have invented certain new and useful mprovements in Journal-Box Coolers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My' invention relates to new and useful improvements in car journal boxes wherein a cooling device is applied to prevent the said journal boxes from becoming overheated and causing what is called a hot box.

Heretofore it has been the practice to pack Cotton waste and oil around the axle of the car wheels to keep the same lubricated and considerable trouble has been experienced by the bearing becoming hot and the waste starting to burn after the oil supply has been substantially exhausted. There is caused considerable delay and expense both in time and the cost of replacing the journals. `With my new device, the journal box will be kept cool at all times and the .evaporation of oil will be less rapid so that the car axle will be lubricated for a much longer period of time than a journal box of the ordinary construction.

The Object of my invention is to provide a device which will be adaptable to any journal box now in use without the necessit-y of preparing the ournal in any particular way other than drilling a hole through the side thereof.

It has been the practice heretofore to form a journal with funnels extending* laterally therefrom which are adapted to cool the bearing, but inasmuch as there are a great number of cars in use at the present time which are not provided with these funnels, my invention will place this method of cooling within 'the reach of all cars now in existence without the necessity of replacing each journal box as would be necessary with the patents heretofore issued.

Vvith the above, and other objects in view, I will now proceed to describe my invention more fully in the annexed specication and. drawings, in which;-

Figure 1 is a section of the journal box showing my invention applied thereto; Fig. 2 is a detail perspective of a fragment of my invention showing` the sleeve attached to the clamping members which may be applied to the side of a journal box; Fig. 3 is an end elevation of the funnel, and Fig. l is a detail of the adjusting ring.

Referring more particularly to the drawing's, 1 indicates generally a car journal box; 2 is a frame having' project-ione 3 formed at each end which are adapted to receive the clamping bolt 4:. This frame is substantially rectangular in shape and is provided at each side thereof with an outwardly projecting sleeve 5, being cut away, as shown at G. Slidably mounted in the sleeve is a funnel 7 having a tubular stem 8 externally threaded which is adapted to communicate with the interior of the journal box 1. At the mouth of the funnel 7 I preferably pro- 'vide a wire netting or ltering means 7'.

Rotatably mounted between the sections of the sleeve 5 I provide a ring 9 which is internally threaded to co-act with the threads on the stem 8 of the funnel 7 and adjust the same to the necessary position in the journal box. Suitably spaced around the periphery of the ring 9 are grooves 10 which are adapted to receive a spanner or other wrench to provide for the turning of said ring in adjusting' the funnel. In the edges of the ring 9 I also provide recesses 11 which are adapted to register with recesses 12 in the sleeve 5 and receive a pin or other looking means and thereby prevent the ring from being accidentally turned.

The frame 2 is composed of three sections, two L-shaped sections indicating 13 and 14 and one U-shaped section, as indicated at 15. These sections are joined together by means of flanges 16 which are connected by means of bo-lts or rivets 17.

In operation, when it is desired to place my improvement on a car journal box of the ordinary construction, holes are drilled in the sides of the journal box and the frame 2 clamped around the said journal box in such a manner that the project-inn; sleeves 5 will register with the aforesaid holes. The stem S of each of the funnels 7 is then inserted in the sleeve 5 through the rings 9 which are turned until the funnel is brought into the proper relation with the holes in the sides of the journal box. A. pin or other fastening means is then inserted in the registering recesses 11 and 12 and the ring's are thereby prevented from turning and forcing the stems 8 of the funnels 7 out of the proper relation. with the holes in' the journal box? l/Vhile in the foregoing. I have show-n and described the preferred embocliment ,of my nvention, I wish it to be unclerstoocl that I may change the particular arrangement of the parts without' in any way departing from the Scope of the cl'aim annexed.

Having` thus fully describecl my invention, what I Claim is 2- In co'mbination with' a journal box, a cooling device, comprising a trame* eomprising` two substantially I'd-shaped members and one substanti'al ly U'-sh`ape`cl member having .sleeves extencling* therefrom, fl'anges extending from the' sicles: of said: sleeves and adapted to be clampecl firmly together, rings internecliate the ends of said sleeves and come` munieating` with the interior thereof, threads internally of said rings, funnels having externai ly threaded Steins adaptecl to coperate with the aforesaid internally threadecl ring's Whereby said funnels may be adjustecl with relation to the journal box, and means for cla mping the whole firmly to the sicles of Copi'e's' of this p'a'tent may'be obtai'ned for five cents each, by addressng the Commissioner of Patents, Washington, D. C.
